Archaeological site Puma Punku

Pumapunku or Puma Punku is a 6th-century T-shaped and strategically aligned man-made terraced platform mound with a sunken court and monumental structure on top, near Tiwanaku, La Paz [1]. It is part of the Pumapunku complex, at the Tiwanaku Site, an ancient archeological complex in the Andes of western Bolivia that has been designated a UNESCO World Heritage Site [1]. The Pumapunku complex is a collection of plazas and ramps centered on the Pumapunku platform mound [1]. Construction of Puma Punku is believed to have begun after AD 536 [1]. The fragments of five andesite gateways with similar characteristics to the Gateway of the Sun were found [1]. The largest of Pumapunku's stone blocks is 7.81 metres long, 5.17 metres wide, averages 1.07 metres thick, and is estimated to weigh about 131 tonnes [1]. Notable features at Pumapunku are I-shaped architectural cramps, composed of a unique copper-arsenic-nickel bronze alloy [1].
